Greetings all I am in good shape and lean, however I am 6'6 and 225lb. I can't really be much thinner and stay healthy so lossing weight isn't an option. Will this weight limit me with falls?

i don't think it would limit you too much.  if you started getting into really high drops or jumps, then it probably would, you would have more momentum than someone 150 lbs (momentum = mass x velocity).  obviously since you weigh more, gravity is going to exert a higher force vector upon your mass.  during your training, spend alot of time focusing on your rolls, and rolling landings.  become a wizard at transmuting vertical momentum (in this case, from a downward drop) into horizontal momentum (ala the roll).  the point is, you want to spread the impact over as much space as possible, both along the ground, and along your body.  and remember that parkour can, but does not necessarily mean high drops/jumps.  those can be a part of it, but they are not required.  so go slow, pay alot of attention to your landings, have fun and be safe.  and good luck  Smiley

Thanks for the swift response.

So far the drops aren't a problem but some guys in my town drop like rain! They seem not to feel the falls. They are all alot smaller than me. I guess I might have to specialize in low altitude tricking.

personally, i can drop or jump from very high, and whether i roll on the landing, or just drop and slap the ground, i pop right back up and feel nothing except the desire to do it again.  i've been doing that for years though, literally ever since i was a little kid.  so, without really intending to do so, i've built myself up to that over a couple decades.  i also only weigh 150 lbs., so i'm sure i have an advantage in that way.  proper body mechanics play a huge roll, and i tend to have very good instincts when it comes to that sort of thing.  i'm sure you could develop your dropping ability a fair bit, but there's heaps that can be done without going high up.  everybody type has it's advantages.  so yeah, train up on your rolls and landings, but no need to concern yourself with going airborn... keep that to a minimum to be safest  Smiley

Thanks again for the fast response. This board seems to be very active. I am a member of alot of boars, to match my interests, and a response in a single day is rare.

Right now I am into long vaults. They feel good to me, and due to my 6 foor 6 inch frame I can vault alot farther than others. I guess I shouldn't compair myself to others though as it only discourages me. I guess we all focus on that which we wish we were better at. For instance, I can bound over walls 14 feet high with ease and my friends strungle with it and consider it a mile stone to make it. But when I do it they say, "well of course you can your frigg'in 6'6." But when I feel the nerves about a drop they dont understand it. Its like minority status in parkour or something. I'm so unlike those I am around its hard to gauge how I am advancing.

I also have a hard time with intricate rail work involving alot of "under and though" techniques. I barely fit through holes my counter parts can shoot through with ease.

Finding my place I guess.

Thanks agian for the responses.

as far as gauging your advancement, i would say gauge it against where you started, not against if you are catching up with what other people can do.  best way would be to start a training log.  where you are now, and what you'd like to improve, and then keep writing in it.  reading back on it every so often will be a great indicator of how and where you are advancing, or stagnating.

Well, I wouldn't let weight stop you. Nothing is standing in your way but hard work. As long as you condition enough and practice enough, along with street smarts not to jump off to high, you'll be able to do fine.

Just another thing about the falls.  I'm pretty sure that everything falls at a constant rate of about 9.8 m/s².  Meaning that everything falls at the same speed, and also that the speed you're falling at is increasing by 9.8 meters per second.  So after the first second that you are falling you're falling at 9.8m/s, and after one more second you're falling at 19.6 m/s. 

Be careful and have fun!

Nice input but this isn't so much about falling as it is about impact which requires much more physics.

I am 6'2", and although it is a few inches shorter than you, I think it's close enough to identify. I haven't yet had any problems being tall and doing parkour with the exception of trouble with wall top-offs sometimes. I have become proficient with underbars, which alot of people thought I would have trouble with. What I've found is that your body will find ways to adapt, whatever your size, so don't worry, just train alot.

There is a guy named Will (willgrind) in Colorado who is about your height, and he is pretty good. He used to train with the Tribe before he moved to Colorado. He posts on here from time to time. You might talk to him. I'm sure he could give you some tall man's insight into parkour.

The taller you are the longer the deceleration on impact (Thus lower force), so height does have an impact absorption advantage. Also, for drops where you hang down first (Such as the Demi tour, half turn), you actually drop less distance because of your height.

But their is more weight, so I'm sure that affects things.

Demon did a huge experiment/study with a biomechanics professor about all this stuff. There is a thread on it somewhere in here. Not sure if the final results are out yet, but the discussion in the thread was interesting and is worth a look if this is a concern of yours.

I am a tiny woman, so I can't comment directly to your question. Smiley
